Answer:
Option (3)
Step-by-step explanation:
Given polynomial is (x³ - 2x² - 13x - 10).
If (x - 5) is a factor of the given polynomial, other factors can be found by the synthetic division.
5) 1 -2 -13 -10
<u> - 5 15 10 </u>
1 3 2 0
Therefore, other factor of the given polynomial will be (x² + 3x + 2)
And the factored form of the polynomial will be,
(x - 5)(x² + 3x + 2)
Option (3) will be the answer.
C. 7
f(3) means find the f(x) when x =3
Using the chart
f(3) = 7 when x =3
